Terminology and Concepts of PA Server Monitor

PA Server Monitor runs on a Windows computer and monitors the condition of servers and other equipment on your network. The following graphic shows the basic structure of a network that is using PA Server Monitor.

The PA Server Monitor product is composed of two parts: a graphical user interface that we call the Console, and a background process called the monitoring service. You see the Console when you launch PA Server Monitor from the desktop. The service is invisible and has no user interface of its own.

The following diagram will give you a better idea of how the two parts of PA Server Monitor work together.

The service is the part of the product that performs the monitoring of the network. The service is set up so that it runs automatically when Windows starts. The Console does not need to be running in order for monitoring to take place.

The Console and the service are installed at the same time when you install PA Server Monitor from the setup application.

Product Terminology

PA Server Monitor is based on the concepts of Monitors and Actions.

The PA Server Monitor product contains different types of Monitors that watch server resources. These monitors trigger Actions (such as notifications or server operations) as well as record monitored data to a database for report generation.

Monitor

A Monitor periodically checks a computer resource and optionally compares the measurement to a threshold value that you set.

You can create a new Monitor by selecting its type and filling in the required parameters.

Error Condition

An Error Condition happens when a value of a resource that is checked by a Monitor is outside the acceptable range for that value.

One example of an Error Condition is space on a particular disk volume falling beneath a defined threshold. Another example of an Error Condition is lack of response to a "Ping".

Action

An Action is an activity that PA Server Monitor performs as part of its response to an Error Condition. All Actions are created from any of the available Action Types.

Examples of Action Types are sending e-mail, execution of a script, or writing text to a log file.

How Monitors And Actions Work Together

Monitors and Actions are always defined within PA Server Monitor as follows.

When an Error Condition occurs, the list of Actions that is attached to the Monitor is executed. Each Action in the list is executed, in the order in which it appears in the list. This list is called the Error Actions for the Monitor.

When the Error Condition stops occurring, another list of Actions that is attached to the monitor may be executed. This list is called the Fixed Actions for the Monitor. Each Action in the list is executed, in the order in which it appears in the list. Its entries are executed when the Error Condition has been fixed. Not all monitors have Fixed Actions.

How Monitors and Actions are Created

Monitors and Actions may be created in any of three ways:

In addition, you can manually edit any of the existing Monitors, and you can manually edit the Actions that are attached to the Monitors. You can add Actions to existing Monitors or delete them, and you can delete unneeded Monitors (and their Actions) as necessary.
